Asia accounts for 99 of the world’s top 100 environmentally risky cities, with China and India accounting for 4/5 of the total.

According to the risk assessment report released today, Asia accounts for 99 of the world’s 100 highest environmental risk cities, with four out of five of them located in India or China.

The report found that more than 400 major cities around the world, with a total population of about 1.5 billion, face “high” or “extreme” risks from a variety of pollution, reduced water supplies, deadly heat waves, natural disasters and climate change shocks.

Jakarta, Indonesia’s capital city, which is suffering from pollution, flooding and heat waves, tops the list as its strata continue to sink.

But India, which has 13 of the world’s top 20 riskiest cities, may face a more worrisome future than any other country.

According to the Global 576 Cities Index compiled by Verisk Maplecroft, a business risk analysis firm, Delhi (Delhi) ranks No. 2, with Indian cities including Chennai (Chennai, No. 3), Agra (Agra, No. 6), Kanpur (Kanpur, No. 10), Jaipur (Jaipur, No. 22), Lucknow (Lucknow, No. 3), and India (Lucknow, No. 4). Lucknow (24th).

Mumbai, with a population of 12.5 million, is ranked 27th.

Air pollution causes more than 7 million premature deaths around the world each year, up to 1 million in India alone. In terms of air pollution alone, India accounts for 19 of the top 20 cities in the world with at least 1 million people in metropolitan areas with the highest air quality risk, with Delhi leading the way.

This air pollution assessment focuses on the impact of fine suspended particulate matter (PM2.5), which is harmful to health and is released in large quantities by burning coal and other fossil fuels.

The only city outside of Asia to rank among the top 100 environmental risks is Lima, the capital of Peru, a South American country.

Although wealthier than India, China also faces more difficult environmental challenges. According to the report, China is among the top 50 cities in the world plagued by water pollution, including 35 of them. And of the top 15 cities facing severe water shortages, China has 13 of them.

Will Nichols, the first author of the report, said the very different political systems and levels of development may ultimately benefit China. In China’s case, he said, “the emerging middle class is increasingly demanding cleaner air and drinking water, and that’s reflected in the government’s goals.”
